Application filed September 19, 1912.

siding in lrooltlyu borough. in the county oil{iugs. city and State o'l New York, have invented certain new and useful Improvevnients in 'l` vpc\\'riting Machines. ol which the.lollmvingis a specilication.

'flhe present invention relates jniularily to means vlor 'facilitating thc positioning oi work-.pieces at the center of a typewriter For this purpose a work-piece centering scale is located at the introductory side' ol' `the platen, being preferably mounted at the upper rear cndoi the paper table behind the platen. so that work-pieces may he centered on thc paper table by means of thc scale hel'ore they have been fed forward between the platen and the feed-rolls to the printing position. By placing the scale at the intake side of the platen the work-sheet may be accurately centered before it has been gripped by the feed-rolls, and without the necessity of releasing the feed-rolls and rcadjusting the work-sheet after it has been placed on the platen.

The scale preferably comprises two series of numbered graduations commencing with zero at or near the ends of the scale and numbered toward the center of the scale, the distance between the zero points being equal to the length of the full line of writing. A Work-sheet may therefore be centered on the scale by so positioning theV work-sheet that the same scale numbers appear at each edge of the sheet. The scale is also provided with graduations or markings extending beyond the zero point at each end of the scale to enable a work-sheet wider than the full-length line of writing to be centered thereon.

A letter-space scale may be used in conjunctionwith the paper-centering scale, the graduations of the two scales beingr in register, that is, the zero point on the letterspace scale being directly in front of or in line with the zero point on the centering` scale. A marginal stop eontrolling'the inargin on the left of the 'work-sheet is adjustable along the letter-space scale. which, .in conjunction with 'the paper-centering scale, enables the stop to be set for any desired margin for a work-sheet of any width. In other words, the distance ol the margin stop from the scale number in register with the Specification of Letters Patent.

yedge of the work-sheet, represents the width Ithe-center 3, which is marked"40" in this case, is preferably ot' a tubular construction, so as to Conform with the curvature Je (Flg.

yQ) of the bead of the paper table 5 on the typewriter carriage (3. A boss T is fastened to the scale 1 near each end thereotl and within the same to hold a screw-'8. Then this screw is turned outwardly. it bears against the inner surface ot' the bead of the 'pa Jer table This screw clamp is rendere more effective by having the lugs 7 slightly undercut at 10 to allow the edge 11 of the tubular bead of the paper-table to catch beneath the lugs; this affording a firmer grip of the scale 1 on the said paper table.

It will be noted that the lugs and screws are within the bead, preventing the paper or the sleeve of the operator from catching thereon.

The work-sheet 1Q is centered by placing it over the scale 1. as shown diagramnnitically in Fig. 1, and adjusting it sc that the same number of graduations remain uncovcrcd at either side. The work-sheet must be adjusted toward either the right or lett, until it registers with like graduations at its side edges.

To facilitate thc setting ot' the marginal stop 13, which governs the margin upon the left of the work sheet- 12. the graduatious 2 or. thc right half of thc scale 1, are arranged to coincide with the grarluatious 11 on the, typewriter letter-space scale 15.

'1"hctvpewriter carriage (i is usually wider than the writing liuc ot the typewriter. to receive paper wide enough to allow a mar- `in on each side of the written matter. The sheet 12 may overlap the zero or starting point of the graduations 2 and 8 on the scales 1 and 15. Auxiliary graduations 1G extend beyond the zero marks on scale 1, so that a sheet may be centered by means eoA of the graduations 16 beyond th'e zeros at each end.

Variations may be resorted to Within the scope of the invention, and portions of the improvements may be used Without others.

Having thus described my invention, ,I claim:-

1. In a typewriting machine, the combination with a paper table having a bead at its upper end, of a scale curved toconform to the shape of said bead, and a clamping device on said scale extensible within.the\ bead to clamp the scale on the bead.

2. As an article of manufacture, a type writer scale semi-cylindrical in cross section and provided with clamping devicesr on the interior of the scale.

3. As an article of manufacture, a typewriter scale substantially semi-cylindrical in cross section and comprising blocks fixed to the inner surface of the scale, and clamping members threaded into said blocks.

4. In combination with a paper table having a bead at' its to) edge, a semi-tubular scale conforming wit the curvature of said bead, and means located within'the Semitubular scale to clamp the scale to the bead.

5. In combination with a paper table havinga bead at its top edge, a semi-tubular scale conforming with the curvature of said bead, and clamping means located substantially wholly within the bead and scale and concealed therein to fasten said scale on L. table.

6. In a typewritin machine, the combination with a revolub e laten and its frame, of a paper shelf at the introductory side of the laten, and a centering scale on said, shelf extending from Vone side to the other thereof in position to be overlaid by a work sheet, said scale having graduations readin' toward the center from two zero points an other graduations at the outside of the zero points, one zero point agreeing with the Zero )oint of the usual frame scale.

T. ln a typewritinv machine, the combination with a revolube platen and its frame, of a paper shelf at the introductory Side of the platen and a centering scale on said shelf extending from one side to the other thereof, in position to be overlaid by a work sheet, said scale having points coincident with the beginning and end of the usual frame scale, and graduations of the same magnitude as the usual frame scale graduations, extending beyond said points on said first mentioned scale, whereby a sheet of paper of any width that can be accommodate( by the platen frame, may be centered and the wdthof the margin determined.
